Some public school systems in Maryland are dismissing students early ahead of possible snow Friday afternoon.

Light snow starting at 1 p.m. could disrupt the afternoon and evening commute on untreated roads, according to the National Weather Service. It’s unlikely that snow will accumulate more than an inch, though.

The weather service issued a high-wind warning, an extreme-cold warning and a hazardous-weather outlook for parts of Maryland starting Saturday morning.

Last month, a winter storm dumped 8 to 12 inches on parts of Maryland, and some school systems just returned to a regular schedule this week. Remnants of the storm remain around the area.
